Differential options for stock 10-bolt in my '00 Z28 I'm going to be installing 4.10's soon, and I'm thinking that's also the time to change out the diff.
I believe all the LS1's have a posi diff from the factory, but which brand might vary (not sure)
A friend recommended a Powertrax Locker which he says was not nearly as harsh as a Detriot Locker, but held up to all kinds of abuse.
I did a search but couldn't really find many people running this diff on a stock rear end.
Any thoughts? I'm not ready to spend any more on a 12-bolt or Ford 9", so this thread is really to discuss:
- Should I upgrade the diff while I do gears?
- If so, what diff? I'm leaning towards this Powertrax.
Thanks, in advance.

I wouldn't worry about it. if you're keepin the 10bolt then get a TA cover and a girdle to help it out. But that's just a band-aid fix until you can afford to upgrade the whole rear end

When people say the 10 bolt breaks easily... what exactly breaks? The spider gears?
The same friend who recommended this diff said he went through 2 sets of spider gears in his blown S10 w/ 10-bolt, before he finally decided to add this diff... after that, it stood up to all his abuse.

More often than not its the pinion getting a shave. Simply not enough metal in a 7.625 inch ring and pinion to make them worth anything.
FWIW I have the fancy $500 Eaton Posi in my 87 w/ a built and stalled 700r4. However, after a couple bad ring and pinion installs(noise) I could have almost bought a 9 inch once the smoke cleared.
So much for a budget build...
